False information given then charged more

I am not happy with the information I was provided. I called in in April via the Telkom customer care line wanting to cancel my subscription as I was not happy to be paying R185 for 10Gb+10Gb. The consultant that was assisting me said I could not cancel as I took out the contract last year. As disappointed as I was, I acknowledged that. She further on went on to say that she can increase my Gigs and keep it at the same price. So it will be 20Gb+20Gb for R185. I asked her if I will be paying anything more, she reassured me "NO, I will not be paying a cent more".

May came, and my debit order is R244.56. I called in again, I was told it is a once off payment as there was an adjustment made on my account. June, still the same amount debited. I called in they said I shouldn't worry as I will only be paying this amount for 3 months at most then I will go back to paying my initial fee of R185.

I went to inquire about this at a Telkom shop and I am told that 244 is my new payment as I did an early upgrade. I NEVER REQUESTED FOR ANY UPGRADE.... I REPEAT... I NEVER REQUESTED FOR ANY UPGRADE AT ALL. So why should I be paying more because of a consultant that gave me false information. I am tired of hearing different stories, I want my account back to R185 and I do not want to pay a cent more.
